-Case by case. Normally it may take several months to one year.
-It will be sent to the petitioner because it is convenient for USCIS to that. But the form should be completed/signed by the beneficiary. The petitioner can be chosen as the agent.
如果隻寄給beneficiary,那要寄到中國,可能要花費比較長的時間。請問有可能讓NVC送電子郵件嗎?
-It can be scanned and sent by email even if after it is been signed. Print it out using color printer.
